New arguments

[pcf0]

This PR includes also #603.

I have added a number of arguments that I use in my project via extensions. The namespaces are structured according to the ffmpeg documentation, because in my opinion the parameters of FFmpeg and their interaction are already very complex and confusing. That helped me to understand them. I have therefore also added (currently unnecessary) marker interfaces such as IMuxerArgument and IDemuxerArgument.

I hope that this will also be helpful for this project.

There is no particular reason these videofilter arguments are not more directly supported, other than the fact that this library does not aim to support all ffmpeg arguments directly as that would too complex for a wrapper library. Instead, the aim is to support commonly used arguments and then support the remaining indirectly but still conveniently, i.e. through WithCustomArgument

I think u can write your own library with extension.
If you want a complex filter and argument system you can look at https://github.com/tqk2811/FFmpegArgs
